I'm sorry your BS-player crashed. I'm also sorry because I don't have answers for either of your questions. I can't remember what either Sherlock or Mycroft said specifically in these instances. I managed to download the episode on my hard drive, but I don't have time to watch it. As it is, I'm skipping a trip to the movie theatre today because of all the things I have to do. However, maybe someone else will see this thread and be able to give you an answer. I'll certainly let you know if I find out anything myself. :-)
